Are there any statistics on programming languages used for games?

I mean something like ...
Visual C++ - 500 professional games in last 5 years
C - 20 professional games in last 20 years
C++ - 200 professional games in last 15 years

One of the reasons I ask is because I am a professional programmer (C/
Unix/Oracle) but I am bored with that and since I am also a
mathmatician (College Professor) and I love games, so I thought I
would try my hand at programming some games.  I wrote a few "home
quality" only ones in VB and C.  But, I am talking about the nice
graphics ones.

I see all kinds of books like C# , C++ , Visual C++, Java,  etc....
for Game Develepment.
I don't want to waste my time in a language that most professional
developers don't use.

So, can someone tell me what are the best programming languages to use
for game development.  Also, what about tools that developers use
(like for shading, skinning, etc).

Also, any statistics on DirectX, OpenGL, etc...

I am just trying to save time by finding out what is used most.

Thanks!
